You asked: What type of crossover are you planning on using?

My first stab at this will be the flexible (but oh so cheap) Behringer crossover/EQ unit...I think it is called DEQ2496. I haven't bought one yet, but they are usually in the $250 range new and delivered. This unit offers options for 6-48 dB/octave crossover slopes at any combination of frequencies with time delays for all channels, 1/3 octave plus parametric eq, auto eq, hundreds of presets and more. The biggest challenge I have heard about with using this (or any digital pro gear) is to correctly match input and output levels with home hi-fi equipment...the pro gear being optimized for a roughly 10-15 dB hotter line out for best S/N. Many folk have complained about harshness and grain when using this unit between say a pre-amp and main amp, but the majority opinion seems to be that when the Behringer is run at full resolution--by upping the preamp-out levels to close to 2-4V and padding down the analog outputs--it sounds just fine.

Thanks for your interest and encouragement,
David
